INTRODUCTION
With 940 genera and almost 5,000 species, Pentatomidae is one of the largest families within
Heteroptera (), and it is represented in all zoogeographical regions although the tropical and subtropical faunas are the most diverse (). The pentatomids are known as stink bugs because they produce a disagreeable odor by means of scent glands ). More than 1,400 species of stink bugs are represented in the Neotropics, while in Argentina 103 genera and 271 species are recorded (Dellapé G. et al., 2015;t ;;, ).
The stink bugs are mostly phytophagous and feed by inserting their stylets into the food source causing injury to plant tissues. During the feeding, they may also transmit plant pathogens, which increase their potential damage (). Phytophagous pentatomids are the most economically important group among the Heteroptera, because of their diversity, the wide range of host plants fed upon -from vegetables to trees-, and the frequent damage to agricultural production. The economic importance of these insects varies greatly from species to species, and within a species, depending on the plant attacked ;;). In the Neotropics, more than 20 species of phytophagous pentatomids cause losses or damage in several crops such as cotton, rice, corn, soybeans, sorghum, tomatoes, among others; and practically all these species are recorded in Argentina , ;).
The only pentatomids with predatory habits are the asopines (subfamily Asopinae), whose species have been increasingly studied as potential agents of pest control (,). In the Neotropics, Podisus nigrispinus (Dallas) is well studied and has great potential for controlling populations of some phytophagous species (Saini, 1994;). Other species that have been studied and are represented in Argentina are Alcaeorrhynchus grandis (Dallas), Brontocoris tabidus (Signoret) and Tylospilus nigrobinotatus (Berg) ; .
Since the last work on distribution of Argentinean pentatomids by Dellapé G. et al. (2015), new field trips have been carried out allowing to update the distribution of the stink bugs from Argentina. In this contribution, two genera and eight pentatomid species are recorded for the first time from Argentina; also, the distribution of other previously recorded pest and non-pest species is extended, the economic importance of some species is summarized, and additional information on host plants is provided.
MATERIAL AND METHODS
The material studied comes from field trips carried out by the author, her work group, and other colleagues in several localities of Argentina. Whenever required to confirm identification, the genital capsule of males and genital segments of females were dissected and cleared with a saturated potassium hydroxide solution for observation; dissected genitalia were preserved in microvials with glycerin. All specimens were deposited in the Entomological collection of the Museo de La Plata, Buenos Aires, Argentina (MLP). Furthermore, material deposited in the entomological collections of the Museo Argentino de Ciencias Naturales, Buenos Aires, Argentina, (MACN), Instituto Miguel Lillo, Tucumán, Argentina (IMLA), and MLP was also studied. Photographs of the species were taken using a Nikon SMZ 745 stereomicroscope and stacked with the Zerene SackerTM software. The species were listed by subfamily and tribe according to the sed by Rider et al. (2018).
RESULTS
In this contribution, the genera Cataulax Spinola and Grazia Rolston, and the species Acledra breviscutata Breddin, Banasa peruana Thomas, Banasa dolabrata Thomas, Cataulax froeschneri Grazia, Campos & Becker, Grazia tincta (Distant), Mayrinia variegata (Distant), Mitripus acutus (Dallas), and Tylospilus peruvianus (Horváth) are recorded for the first time from Argentina. The characters used for the identification of these genera and species are provided. In addition, the geographic distribution of 27 pentatomid species is expanded, and new records of host plants are reported for Alveostethus pseudopolitus (Ruckes), Antiteuchus mixtus (Fabricius) and Pellaea stictica (Dallas). On the other hand, information on the economic importance of pest species in Argentina: Euschistus heros (Fabricius), Chinavia impicticornis (Stál), Nezara viridula (L.), Arvelius albopunctatus (De Geer), and Piezodorus guildinii (Westwood), is summarized. With the results of this update, 105 genera and 279 species of pentatomids are recorded from Argentina.
